Title: Low nox device of steam boiler
Inventor: WATANABE TADASHI
IPC: F22B31/00
Filed: 1989-05-18
Abstract: PURPOSE:To prevent the separation of suspended matter and dissolved solid in the process of evaporation after their spraying and their attaching to heat transfer surface by condensing the steam generated from a steam boiler itself and spraying the condensed steam into flame. CONSTITUTION:The steam generated in a steam boiler 1 reaches a condenser 7 through a valve 15 and piping 16 by its own steam pressure. Since supply water is stored in a supply water tank 6, the condensed steam radiates its heat here and becomes pure water. The condensed pure water is sprayed by its own pressure from a spray nozzle 3 provided near a fuel injection nozzle 4. Since the running water that is injected from the spray nozzle 3 is pure water (distilled water), it does not contain suspended matter or dissolved solid. There is, therefore, no problem such as their deposition, their attaching to heat transfer surface, hindrance of the heat absorption and ventilation of the boiler, etc.
